Condensing Boiler

[steven wheaton]

I am planning on using a condensing boiler (not combi) in a new installation (no previous CH in an old building) would the new boiler be a sealed system fed by a filling loop directly from the main or would it utilise an F & E tank.(not connecting any gas !)

you decide!! there is that many options out there.think i would install a conventional boiler with a sealed system kit too if i was starting from scratch!!

Smoggs, thanks for the response. The occupant wants a hot water cylinder so a combi boiler is out of the question. Taking into account the energy efficiency regulations a condensing or a system boiler appear to be the answer but i was not sure if either of this needed an F & E tank as with a traditional boiler or whether they can be fed directly from the main water supply via a filling loop therefore becoming a sealed system negating the need for an F & E.
